This is when you get turned on and undo your zipper, pull out your penis and begin to masturbate furiously. You then feel the urge to Sneeze and you reach into your pocket and get out your handkerchief, but you also realise you are also about to blow your load...... Do you put the handkerchief over your mouth to muffle your sneeze, or do you put it over your penis to catch your load of cum - thus preventing your clothes from getting 'stained'?

I was having a good wank before I went to work, then my nose began to twitch & I was about to sneeze and also cum. It was a real 'Hank ahh choo' moment
